2. Figure 1
Genetic linkage map and statistical analysis in F2 (S × MNS) as well as congenic strains. ANOVA, one way analysis of variance for testing the linkage of loci in F2 (S × MNS) to blood pressure; P indicates probability. Blood pressure difference at each locus refers to blood pressure of rats homozygous for the MNS strain allele (MM) minus blood pressure of rats homozygous for the S strain allele (SS) in F2 (S × MNS). Under congenic strains designated as a, b and c, solid vertical bars to the left of the map represent the chromosome regions of the S rat being replaced by the homologous regions of the MNS rat. The entire regions indicated by solid bars and the junctions between the solid and open bars are homozygous MM for all the markers listed in the corresponding positions within the solid bars on the map. Open bars at the ends of solid bars indicate that the exact breakpoints of crossovers are unknown within an interval between markers. The junctions between the solid and open bars as well as ends of the chromosome regions of interest in each congenic strain are connected by dotted lines to the corresponding marker positions on the map. Each thick bar graph at the bottom left of the Figure illustrates the deviation of congenic from S rats in blood pressure for each corresponding congenic strain shown above. Abbreviations are Ace, angiotensin-converting enzyme; Ngfr, nerve growth factor receptor, a newly developed microsatellite marker designated also as D10Mco31; Nos2, inducible nitric oxide synthase; Syb2, synaptobrevin 2; Grm6, glutamate receptor, metabolic subtype 6; Mit-RR1023, D10Mit3 and D10Mit10 are anonymous rat markers[77,78]; and D10M11Mit119, D10M11Mit175 and D10M11Mit84 are anonymous mouse Chromosome 11 markers, D11Mit119, D11Mit175 and D11Mit84, respectively, purchased from Research Genetics (Huntsville, AL, USA).

Localization of a blood pressure quantatative trait locus (QTL) in F2 (S × LEW). Under QTL localization, the thick bar represents ± 1 LOD support interval, and thin lines extending from both ends of the thick bar indicate ± 2 LOD support interval. ANOVA is one way analysis of variance for testing the linkage of loci to blood pressure; P indicates probability. Blood pressure difference at each locus refers to blood pressure of rats homozygous for the LEW strain allele (LL) minus blood pressure of rats homozygous for the S strain allele (SS) in F2 (S × LEW). Abbreviations are: Ngfr, nerve growth factor receptor; Nos2, inducible nitric oxide synthase; Mhcg, Myosin heavy chain embryonic; Grm6, glutamate receptor, metabolic subtype 6; D10Mco31, a microsatellite-based marker newly generated for Ngfr; D11Wox6, anonymous marker provided by Dr. Mark Lathrop (Oxford University, England, UK); D10M11Mit168, D10M11Mit58, D10M11Mit119 and D10M11Mit15, anonymous mouse Chromosome 11 markers, D11Mit168, D11Mit58, D11Mit119 and D10Mit15, respectively, purchased from Research Genetics.

4. Figure 3
Ruling out of the inducible nitric oxide synthase locus (Nos2) as a candidate blood pressure quantitative trait locus (QTL) using a congenic strain. Numbers to the left of Chromosome 10 map are map units in centiMorgans using the Haldane correction in an F2 (S × MNS) population (N = 171). The order of loci on the map has been accurately determined by scoring crossovers during the construction of the congenic strain. Directly under congenic strain d, the solid bar to the right of the map represents the chromosome region of the S rat being replaced by the homologous region of the MNS rat. The open bars at both ends of the sold bar indicate that chromosome crossover breakpoints could not be accurately determined within intervals between markers. The thick bar graph at the bottom right illustrates the blood pressure deviation of the congenic from S rats. Abbreviations are: Nos2 (in bold), inducible nitric oxide synthase; Aldoc, aldolase C; D10M11Mit119, anonymous mouse Chromosome 11 D11Mit119 marker purchased from Research Genetics; D10Mco1, anonymous rat marker provided by H. Dene and O. Dukhanina (Medical College of Ohio, Toledo, OH, USA); D10Mgh6, anonymous rat marker[78]; M, the MNS allele; S, the S allele.
